[0041] For a thorough understanding of the present application, reference will be made to the following detailed description, in conjunction with the accompanying drawings, in which:

[0042] Please refer to Figures 1-4 As shown in the drawings, the sheet structure loading and lifting device according to the preferred embodiment of the present application is suitable to be installed on a vacuum forming machine, the sheet structure is a raw material plate, and the device is used for loading the raw material plate. In other embodiments, the sheet structure loading and lifting device can also be installed on other equipment, and the sheet structure is not limited to the raw material plate, and can be determined according to actual conditions.

[0043] In the present embodiment, the sheet structure loading and lifting device (hereinafter referred to as the loading and lifting device) comprises a rack 1, a lifting assembly 2 and a clamping and conveying assembly 3. The lifting assembly 2 comprises a first driving member (not shown) fixed on the rack 1 and a lifting table 21 connected with the first driving member, the lifting table 21 is suitable to place the sheet structure, and the first driving member is used to drive the lifting table 21 to move up and down; the clamping and conveying assembly 3 is located above the lifting assembly 2 and comprises a pair of fixed frames 34 arranged above the lifting assembly 2 and located on both sides thereof, a clamping assembly 35 installed on the fixed frames 34, the clamping assembly 35 can move relative to the fixed frames 34 under the action of external force to have a clamping state and a releasing state, the lifting table 21 is lifted to a target height, and the clamping assembly 35 is switched from the releasing state to the clamping state to clamp the sheet structure on the lifting table 21.

[0044] Specifically, the clamping assembly 35 includes two rotating shafts 31 arranged in an up-down manner and an upper clamping plate 32 and a lower clamping plate 33 connected with the two rotating shafts 31 respectively, the rotating shafts 31 drive the upper clamping plate 32 and the lower clamping plate 33 to rotate in opposite directions under the action of an external force to make the upper clamping plate 32 and the lower clamping plate 33 have a clamping state and a releasing state.

[0045] More specifically, one of the upper clamping plate 32 and the lower clamping plate 33 is provided with a groove 321, and the other is provided with a fixing tooth 331 matched with the groove 321. In the embodiment, the groove 321 is arranged on the upper clamping plate 32, and the fixing tooth 331 is arranged on the lower clamping plate 33. When the upper clamping plate 32 and the lower clamping plate 33 clamp the sheet structure, the fixing tooth 331 engages with the groove 321 to increase the friction between the upper clamping plate 32, the lower clamping plate 33 and the sheet structure, improve the stability of clamping, and prevent the sheet structure from falling off the clamping assembly 35.

[0046] In the embodiment, the clamping assembly 35 can move relative to the fixed frame 34 in the second direction under the action of an external force to have a clamping position and a transportation position; when the clamping assembly 35 is located at the clamping position, it is switched from the releasing state to the clamping state to clamp the sheet structure located at the target height; when the clamping assembly 35 is located at the transportation position, it is switched from the clamping state to the releasing state to release the sheet structure, thereby realizing the feeding of the sheet structure.

[0047] In order to facilitate the clamping assembly 35 to clamp the sheet structure on the jacking table 21, the feeding jacking device further includes a centering assembly installed on the rack 1. The centering assembly includes a first centering assembly 4 arranged in the first direction and a second centering assembly 5 arranged in the second direction, and the first centering assembly 4 and the second centering assembly 5 can move relative to the jacking table 21 under the action of the sliding block and the sliding rail to realize the centering of the sheet structure on the jacking table 21.

[0048] Specifically, the feeding jacking device further includes a first guide rod 6 and a second guide rod 7 installed on the rack 1, the first guide rod 6 passes through the first centering assembly 4, and the first centering assembly 4 can move along the first guide rod 6; the second guide rod 7 passes through the second centering assembly 5, and the second centering assembly 5 can move along the second guide rod 7 to further improve the stability of the movement of the first centering assembly 4 and the second centering assembly 5 and prevent the first centering assembly 4 and the second centering assembly 5 from deviating when moving towards or away from the jacking table 21.

[0049] Since the sheet structure is relatively thin, during the jacking process of the jacking table 21, when only the middle part of the sheet structure is supported by the jacking table 21, the edge of the sheet structure will be bent, which will cause the clamping assembly 35 to be unable to clamp the sheet structure on the jacking table 21 in the clamping position.

[0050] To solve the above problems, in the embodiment, the feeding and jacking device further comprises a first auxiliary assembly 8 adapted to support the edges of the sheet structure so that the sheet structure as a whole is located almost in the same plane or the edges of the sheet structure can be accurately clamped by the clamping assembly 35. It should be noted that the first auxiliary assembly 8 can move up and down synchronously with the jacking table 21.

[0051] Specifically, the first auxiliary assembly 8 comprises first auxiliary members 81 extending in pairs in the second direction and a cylinder 82 connected with the first auxiliary members 81, the first auxiliary members 81 are arranged on both sides of the jacking table 21, and the cylinder 82 can work simultaneously with the first driving member to drive the first auxiliary members 81 to move up and down synchronously with the jacking table 21.

[0052] Further, the first auxiliary assembly 8 is connected with the fixed frame 34 on the side surface to move in the first direction with the fixed frame 34, so that when the clamping assembly 35 clamps sheet structures of different specifications, the first auxiliary assembly 8 automatically changes the distance to adapt to sheet structures of different specifications, without the need for manual replacement of the first auxiliary assembly 8 or manual adjustment of the distance of the first auxiliary assembly 8, which is simple and convenient and greatly improves the work efficiency.

[0053] Further, the device further comprises a connecting piece 9, which is L-shaped, one end of which is connected with the fixed frame 34 and the other end of which is connected with the cylinder 82, so that the cylinder 82 and the first auxiliary assembly 8 move in the first direction with the fixed frame 34.

[0054] In the embodiment, the device further comprises a second auxiliary assembly 10, which comprises second auxiliary members 101 extending in pairs in the second direction, the second auxiliary members 101 are arranged on the inner side of the first auxiliary members 81 and are fixed on the jacking table 21, and the second auxiliary members 101 move up and down with the jacking table 21 to further improve the support stability of the sheet structure.

[0055] It should be noted that the lengths of the first auxiliary assembly 8 and the second auxiliary assembly 10 are greater than that of the jacking table 21, so that the middle part and the edge part of the sheet structure can be well supported to prevent bending.

[0056] To sum up, the working process of the feeding and jacking device shown in the embodiment is as follows: the fixed frame is adjusted to a position suitable for the width of the target sheet structure under the action of an external force, so that the clamping and transporting assembly can clamp the sheet structure in a stable clamping position; after the position of the fixed frame is adjusted, the manipulator places the sheet structure on the jacking table, the first and second centering assemblies move towards the jacking table along the first and second directions respectively, the sheet structure on the jacking table is centered, then the first driving member drives the jacking table to rise, the first auxiliary assembly is driven by the cylinder to rise synchronously with the jacking table, so that the sheet structure reaches the target height, the clamping and transporting assembly clamps the sheet structure, moves from the clamping position to the transporting position, and switches from the clamping state to the releasing state, thereby achieving the feeding of the sheet structure; when the sheet structure of different sizes is replaced, the position of the fixed frame is adjusted by an external force to drive the adjustment of the position of the first auxiliary assembly in the first direction, thereby realizing the automatic adjustment of the first auxiliary assembly to adapt to sheet structures of different sizes.

[0057] The above is only one specific embodiment of the present application, and any improvement made on the basis of the concept of the present application is considered to be within the protection scope of the present application.
